Nozar Nemati, Deputy Commander of the Iranian Army's Ground Force, announced that eight engineering units from the Iranian army are working on sealing the border with Afghanistan.
The IRIB News Agency reported that Nemati inspected the border wall project between Iran and Afghanistan.
On Tuesday, IRIB quoted Nemati as saying, "The technical and operational work on this significant national project spans 300 kilometres along the shared borders of Khorasan Razavi province with Afghanistan."
He stated that the border-sealing process between Iran and Afghanistan has progressed well, with the necessary infrastructure in place to continue the work using regional and local resources.
He added that obstructing the border with Afghanistan will ensure lasting security along the entire Iran-Afghanistan border.
Earlier, an Iranian army official had mentioned that one of the main objectives of sealing the Iran-Afghanistan border is to prevent the illegal entry of Afghans into the country.
